United States-Patent SAFETY RAZOR BLADE HOLDER WITH- SELF-CLOSINGOPERATION John Guardino, New York, N; Y.

Application October 22,1954, Serial No. 464,045

Y 3-Claims; ((150-605) The invention relates to an. improved doublerazor blade holder: and oneof itsobjectsi is to provide a holder for adouble edge razor blade which can be opened by the movement of theholding hand, and which will close automatically to clamp the blade forshaving.

Another object of the invention is the provisionpf a razor blade holderhaving blade clamping members hinged to open upwardly and outwardlysimultaneously, with a plunger rod for opening both blade clampingmembers, a compression spring for moving the rod to closing pos1- tion,and a knob mounted to slide on the handle of the razor blade holderwhich is coupled directly to the spring actuated plunger rod, so thatthe holding person can with the same hand which holds the razor openboth blade clamping members by a short upward finger movement, cleansethe used razor blade, shake off surplus water and then allow the springactuated rod to close the blade clamping members.

A further object of the invention is to provide means for subjecting thespring actuated plunger rod to screw pressure when it has been shiftedto closed position, so that maximum pressure is developed on the bladeclamping plates or members.

With the above and other objects in view, the invention comprisescertain new and useful constructions, combinations and arrangements ofparts, clearly described in the following specification and fullyillustrated in the drawings accompanying this application, in which:

Fig. 1 is an end elevation of a razor blade holder constructed inaccordance with my invention, shown enlarged, and showing the bladeclamping members in closed position.

Fig. 2 is a vertical sectional view thereof, showing the operatingplunger rod and the blade clamping members in open or raised position.

Fig. 3 is a top plan view, showing the clamping plates in openpositions.

Fig. 4 is an end elevation, showing the razor blade holder closed, innormal scale or full size.

Fig. 5 is a side elevation of the handle tube, showing the vertical orlongitudinal slot thereof.

Fig. 6 is a similar view of a modified form of the handle tube.

Referring to the accompanying drawings which illustrate the practicalembodiment of my invention, 10 designates a handle tube having a spoolshaped bushing or extension 11 coupled thereto, as by the screw threads11a.

To the upper end of the extension or bushing 11 a frame base 12 issecured, by the swaged eyelet or fastener 11b formed on the extension orbushing 11. This frame base is provided with the usual parallel curvededges 13 and 14, which ride against the face of the person to be shaved.

In the axial bore 110 of the extension or bushing 11 a rod section 15 isdisposed, and the upper end of this rod section is bifurcated at 15a andis secured to the blade centering bar 16, which is movable with the rodsection. The rod section 15 may have a swivelled connec- 2,775,031Patented Dec. 25, 1956' Tree 2 tion at 17 with the lower rod section 18,which is provided on its lower end with collar 19, secured thereto bythe cross pin 20;

The collar. 19has a free sliding fit in the handle tube 1'0, and on theouter side of the handle tube a cylindrical sleeve 21 is slidablymounted, and the outer ends of the cross pin 20slid'ably extend throughthe aligned slots 22 and 23. ondiame-trical opposite sides of the handletube, and pass through. the wall of the sleeve 21 and are headed againstthe outer surface of this sleeve.

The upper end ofv the-sleeve 21 is formed with an external bead 21a and.provided with an external button 24, fixedth'ereto, as bythe pin 24a,and shown to be small in diameter; Thebead'forms a-thrust shoulder formanually pushing the sleeve. upwards on the handle tube. Any formof'fixed. connection, as brazing or hard soldering, may be used forsecuring the button in place.

A coil spring 25 is mounted on the lower rod section 18, and at itslower end engages the collar 19 and at its upper end engages the washer26, disposed against the inner end of the bushing or extension 11. Thisspring exerts pressure to force the collar 19 downwardly, and as thecross pin 20 connects this collar to the rod section 18 and to theexternal sleeve 21, through the aligned slots 22 and 23 of the handletube, the sleeve 21 will also be forced downwardly.

The centering bar 16 is connected at one end to the end link 27 of therazor holder, and at the other end to the end link 28. The link 27 ispivotally connected to the lever ends 29 and 30 of the blade clampplates 31 and 32, and the link 28 is pivotally connected to the leverends 33 and 34 of the same clamp plates, all in the usual manner.

The coil spring 25 norm-ally holds the clamp plates in closed positions,as shown in Fig. 4, but by manually pushing the sleeve 21 upwardly onthe handle tube 10, the central rod will be moved longitudinally toraise the centering bar 16 and thereby tilt both blade clamp platesupwardly and outwardly to open positions.

The external sleeve 21 is long enough to always cover the two side slotsof the handle tube, and the lower end of this handle tube is providedwith a plug 36 which is enlarged to provide a hand rest to receive thethrust of the hand when the sleeve 21 is shifted upwardly to open therazor blade holder.

The handle tube may be formed with a slot 35 on each side thereof,having a short lateral and diagonal extension 35a on its lower end, sothat by slightly twisting the sleeve 21 the pin 20 will ride in theseoffset slot portions and additional pressure will thus be imposed on theclamp plates to hold the razor blade in place.

My invention provides a razor blade holder which may be opened by onehand, and by the same hand which uses the razor holder for shaving, bysimply pushing the external sleeve or its button, against the resistanceof the enclosed coil spring, so that the holder may be fully opened toflush soap and hair ends from the holder, and then to replace the bladewith a fresh blade.

This self-closing razor holder utilizes the hinged blade clamping platesand operating links, basically disclosed by an expired patent, toprovide a one hand operated razor holder which will automatically close,to safely protect the enclosed razor blade, so that it cannot be injuredby accidental contact with other objects, or displaced from its correctcentered position under the clamping plates.

It is understood that various changes in the details of construction,their combination and arrangement, may be made in carrying out theinvention defined by the claims.

Having described my invention, I claim as patentable:

1. The combination of a double edge razor blade holder having a tubularhandle and a holder base secured to the upper end of the tubular handle,clamping plates, links disposed at the opposite ends of the base andhaving pivotal connection with the clamping plates to rock the same, arod sliding through the handle and having operating connections with thelinks to open and close said clamping plates; of a sleeve slidable onthe handle, a spring within the handle for actuating the rod downwardlyin the handle, and a pin having its outer ends secured to the sleeve andsliding longitudinally of the handle, said handle being formed withopposing slots through which said pin freely extends for slidingmovement.

2. The construction set forth in claim 1, the handle having longitudinalslots provided with diagonal lateral end portions and the pin beingmovable into said diagonal end slot portions to lock the clamping platesin clamping position.

3. The combination with a double edge razor blade holder having atubular handle and a blade holder base secured to the upper end of thehandle, clamping plates pivotally connected with the base to clamp adouble edge razor blade against the base, a rod sliding in the handleand having operative connections with the clamping plates to move thesaid clamping plates from blade clamping position to raised openposition and to return the clamping plates to blade clamping position, aspring enclosed by the tubular handle for moving the rod downwardly toclose the clamping plates to blade clamping position, a pin connectedtransversely to the rod, the tubular handle being formed with a slotthrough which the pin projects, and a member mounted on the pin andslidable on the outside of the handle and providing means for the manualshifting of the rod against the pressure of the spring to raise theclamping plates to blade releasing raised position, said spring reactingto force the rod downwardly when manual pressure is released toautomatically close the clamping plates to blade clamping position.
